HIGH INTENSITY AEROBIC EXERCISE AFTER STROKE
Bibliographic record
Abstract
Over 100 million people worldwide are currently living with the effects of stroke. Aerobic exercise training is a strategy that may decrease the risk of secondary events and reduce the global burden of disability by improving cardiovascular health, cardiorespiratory fitness (V̇O2peak) and mobility after stroke. Exercise intensity is a key component of exercise prescription for promoting V̇O2peak. High-intensity interval training (HIIT) has emerged as a time-efficient alternative to traditional moderate-intensity continuous training (MICT) in stroke rehabilitation. HIIT involves high-intensity exercise intervals that are short (<1 minute, “short-interval HIIT”) or long (>3-5 minutes, “long-interval HIIT”), alternating with brief, low-intensity recovery periods. There is growing interest in implementing HIIT in stroke rehabilitation. Yet, there is a lack of consensus regarding optimal exercise prescription and limited perspectives of people post-stroke who have participated in HIIT programs. This thesis, comprised of three manuscripts, examined the superiority of aerobic exercise interventions for improving cardiovascular health and mobility outcomes and explored the perspectives of individuals post-stroke who have participated in HIIT. We first conducted a systematic review and network meta-analysis of 47 randomized controlled trials (RCT). We discovered that HIIT appears to be the top-ranked intervention for improving V̇O2peak and gait speed compared to lower-intensity exercise in people post-stroke. We then conducted a multi-site RCT that compared 12 weeks of progressive short-interval HIIT to MICT. We found that short-interval HIIT is a time-efficient and effective alternative to MICT for improving V̇O2peak with possible benefits sustained up to 8 weeks post-intervention. Lastly, we explored the perspectives of individuals with lived experience of HIIT and found that HIIT appears well-received, tolerated, and beneficial for stroke recovery. In summary, healthcare and exercise professionals should endorse and implement HIIT in clinical practice and community settings, given the effectiveness and positive participant perceptions of HIIT after stroke.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
